TYPE-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 667,790, dated February 12, 1901.

Application filed September 12, 1900. Serial No. 29,757. (No model.)

To ttZZ whom. it may concern.-

Be it known that I, PHILIP G. NUERNBER- GER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Type-Making Machines, (Case No. 1,) of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to type-making machines by which type-forms, slugs, and the like are manufactured.

The principal objects of my invention are to permit the construction of two slugs or forms simultaneously in a single machine and to accomplish this result by simple, practical, and expedient means.

In machines for making type as at present constructed it is common to first cast the slug or form in a suitable mold and then finish the type or form when in a hardened condition. In one form of machine of this character the type after being cast by an injection of molten metal into the mold is ejected from the mold by asuitable ejector. Itis then grasped by an engaging or grasping device and carried forward. It is then depressed or thrust downwardly by a reciprocating plunger, which forces it into a channel or groove having its opposite ends provided with projections which cut recesses at the opposite ends of the sing, and thereby form the feet thereon. In being carried forward one side is shaved by suitable knives arranged on one side of its path of travel. The slug is thus finished by having its side properly shaved and the feet formed at its ends. In this application for a patent I have shown my invention applied to a machine of this character, although it will be obvious that the invention can be embodied in other machines as well. When it is thus applied, I arrange the mold so that itwill cast two slugs, which are connected with one another by an intermediate web. This double slugin being carried forward after ejection from the mold passes against a knife or cutting edge, which severs the web, and thereby separates the two slugs from each other. Each slug is then forced into a separate channel, which cuts recesses in its ends, so as to form the feet, as before.

As a matter of further improvement I arrange for the removal of the webs which are cut from between the two slugs.

I will now refer more particularly to the drawings, in which portions of a machine embodying my invention are illustrated.

In the drawings, Figure 1 is a side elevation of a portion of such a machine with the operating mechanism in one position. Fig. 2 is a plan view of ashoe forming a part of a traveling head embodied in the machine shown in Fig. 1. Fig. 3 is a vertical elevation of the parts of the machinein a position different from the position in which they are shown in Fig. 1. Fig. 4 is a vertical section taken on line 4. 4 in Fig. 3. Fig. 5 is a plan view of the structure in which the mold is formed. Fig. 6 is a vertical section taken on the line 6 6 in Fig. 3. Fig. 7 is a vertical section taken on the line 7 7 in Fig. 3. Figs. 8, 9, and 10 are views of details of construction. Fig. 11 is a view of the double slug as cast in the mold, and Fig. 12 is a view of the two slugs cut apart from each other and finished.

In the drawings I have shown only so much of a type-making machine as is necessary to illustrate the application of my invention to a machine of the above-specified general character now in use and well known to the art. In this machine a mold A is suitably supported by the machine-framework, (not shown,) so as to maintain a fixed position. A is provided with a mold-cell a, which in the case of my present invention is adapted to form a casting having a plurality of slugs, in this case two. The mold-cell a is shown in Figs. 3 and 5, and the double slug which it casts is illustrated in Fig. 11. The moldcell, it will be seen, is composed of two compartments, each shaped to form a slug, and a small channel connecting these two compartments, which channel casts a web connecting the two slugs. The mold-cell is also provided with a small side extension 8, into which the molten metal is injected. This side extension 8 of course forms a small ear or projection on one of the slugs.

The mold A is conveniently constructed of This mold a base-piece 1, having two upwardly-extending flanges 2 and 3 and a pair of upper strips 4 4, arranged lengthwise upon the base-piece 1 and between the flanges 2 and 3 thereof. The strips 4 4, are separated a slight distance from each other, and each of them is composed of two longitudinal sections, whose ends are separated a distance sufficient to form a cavity for one of the slug portions of the casting and are shaped so as to give the sides of these slug portions the proper form. The forward sections of the strips 4 4 are secured to the base-piece l by screws 5 5 and to the flanges 2 and 3 by screws 6 6. The rear sections are screwed to the flanges 2 and 3 by screws 7 7. The flange 2 is provided with an aperture 8, which forms the metalinlet. Between the strips 4 4 are arranged intermediate pieces or strips 9 and 10. The piece 9 has a substantially rectangular form, as well shown in Fig. 3, and the piece 10 has a cavity 11 and an upwardly-extending projection 12 in advance of the cavity 11. The adjacent ends of the pieces 9 and 10 are separated slightly, so as to form a channel by which metal can flow from one slug-cavity to the other. The whole mold thus constructed is a simple and practical construction and provides a mold-cell having two cavities for two slugs, an inlet to one of these cavities, and a channel connecting them. Consequently the slug X produced by the mold has two slug portions in w, a projection 51", extending from one of the slug portions, and a connecting-web 0& connecting the two portions, as well shown in Fig. 11.

In Fig. 4 is illustrated in dotted lines a metal-pot B, which is understood to contain molten metal and to be suitably supported. in the machine in such position that its spout b will be located opposite the inlet 8 to the mold-cell.

In the machine there is also a reciprocating ejector O, which forms the bottom of the mold-cell and also serves asa means for ejecting the casting. This ejector C comprises a plate-like structure having a transverse section corresponding to the shape of the moldcell, as well shown in Fig. 10. It moves vertically in the channel formed by the sections of the strips 4 4 and the intermediate pieces 9 and 10 and also formed in the base-piece 1, as shown in Fig. 3. It is mounted upon a reciprocating head D, which is understood to be arranged in the machine and connected with suitable power devices, whereby the ejector O is at the proper time given a sufficient extent of vertical reciprocation to eject the casting from the mold-cell. As mechanism for inducing such a reciprocal motion is now in use in similar machines and is well known in the art and also as it forms no part of my present invention,it has not been shown herein.

The machine illustrated also contains a reciprocating head E, which is arranged above the mold A and slides horizontally back and forth upon the same. This reciprocatinghead E carries a gripping or engaging device by which the casting when ejected from the mold is caught or grasped. The form of device illustrated comprises a bifurcated finger 13, arranged at the forward end of the reciprocating head and extending down so as to form between itself and the bottom of the front end of the head a space capable of receiving the casting. The front end of the head is likewise bifurcated, the bifurcations of the head and of the engaging finger being adapted to engage the two slug portions of the casting. The finger 13 is constructed with a horizontally-extending slide 14,which slides upon the top of the reciprocating head E, so as to permit the finger 13 to be adjusted relatively to the front face of the head so as to in effect open and close the engaging device. The slide 14 is conveniently composed of a couple of side strips, Fig. 7, and a rear cross-piece, Figs. 3 and 4, connecting and formed integrally with the side pieces. The latter are arranged to slide on opposite sides of a plate e, secured to the top of the head E. A plate 15 is arranged above and secured to the portion 6 and overlaps the side pieces comprising the slide 14, so as to form an effectual guideway therefor. The rear end of the slide 14 is provided with a thimble orshell 16, and this incloses one end of an expansive spring 17, which acts against the rear end of the plate 6, and thereby tends to draw the finger 13 rearwardly and in efiect close the engaging device. The inner side of the finger 13 is desirably provided with a flat bifurcated spring 18, so as to better grasp the casting. The engaging finger 13 is provided with a stop by which its motion is arrested shortly before the reciprocating head arrives at the end of its rearward stroke. This opens the engaging device sufficiently to insure the introduction of the casting without possibility of interference with the members of the device. The form of stop shown comprises a rod 19, extending from the forward end of the finger and having an adjustable nut 20 and an abutment 21, against which the nut 20 will strike. The nut 20 can be adjusted so as to provide the proper size of opening between the head and the finger when the head is at the rear end of its stroke.

The reciprocating head E is connected with suitable mechanism in the machine by which it is properly reciprocated. As mechanism of this kind is old in the art and forms no .part of my present invention, it has not been ciprocating head then advances, forcing the casting along in front of it until it reaches the spring 18 on the finger 13. This finger l3 and the head thus grasp the casting and carry it forward, the springs 16 and 18 serving to insure a tight hold on the casting. As the casting X is carried forward by the reciproeating head E its web 00 strikes against the knife or edge formed by the abutment 12, Fig. 3, and is thereby severed, so as to separate the two slug portions of the casting. These two portions are carried forward in a separated condition to the forward end of the stroke of the head by being grasped by the bifurcated portions of the finger 13 and of the head. The webs cut from between the slug portions fall into the recess or cavity 11 and thence downwardly and out by the way of a chute 22. The mold A is provided with a block a, having a cutting edge a which cuts off the end 00 of the casting as the latter advances. The mold-strips as are de sirably provided with knives 33 33, by which the two slug portions are trimmed or shaved as they advance in the way in which a single slug portion is trimmed or shaved in machines of this character. The reciprocating head E also carries a plunger F, which is ar ranged to reciprocate vertically in a recess formed in the forward portion of the head. This plunger F is constructed, Figs, 3, 7, S, and 9, with a cylindrical stem 23 and with a fiat portion 24 below the stem 23. The stem 23 works in a suitable aperture formed in an upper piece e, which is secured to the top of the head E. The flat portion 24 works in a recess 25, formed in the front portion of the head, Figs. 3 and o. In this way the plunger F can reciprocate vertically with reference to the head E while being carried backward and forward by it. The plunger F is provided at its forward end with a punch 26, bifurcated at its lower end, so that the fiat ends of the two bifurcations correspond with the length and width of the separated slugs, and the space between them corresponds with the space between the ends of the slugs. The plunger F is reciprocated by suitable reciprocating mechanism. As such mechanism is well known in the art and forms no part of my present invention, it has not been illustrated herein. The mechanism is such that the plunger F is lowered at a time when the head E is at the forward end of its stroke.

In front of the mold A is arranged a channel-piece G, Fig. 5, having a couple of channels 27 27 positioned below the two ends of the punch 26 when the head is in its foremost position. These channels 27 27 are provided with. vertically-extending end projections 28 28. When the plunger F descends, the punch 26 forces the slug portions downwardly from between the spring 18 and the forward end of the head and into and through the channels 27 27 in the channel-piece G. In this way notches or recesses are cut in the ends of both slugs, so as to form the feet thereon.

The fiat portion 24 of the plunger F is desirably extended downwardly, Fig. 3, so as to form a punch 29, which reciprocates above and in the recess 11 when the head E is in its foremost position. In this way the webs cut by the abutment 12 are forced downwardly and their proper exit from the machine assured.

As a desired construction of the head E a wearing-shoe 30 is secured at the bottom of the forward portion of the head, so as to form the upper wall of the mold. This shoe 30 is shown alone in Fig. 2. It is bifurcated at its forward end, so as to form a portion of the channel 25, in which the abutment 12 and the fiat portion 24 of the plunger F work. The wearing-shoe 30 is secured to the head by large screws 31 31 31, one of which is shown in Fig. 3. These screws extend downwardly through the head and fit into the holes 32 32 32 in the shoe 30.

From the foregoing it will be seen that by the operation of the machine a casting having two slug portions is first cast, the connection between such plug portions is then severed and both of such portions are trimmed or shaved, and finally the feet are cut on both of the slug portions simultaneously.

It will be observed that the structure hereinbefore referred to as a slug is in reality a type-form, and it will therefore be seen that the invention can be employed in casting structures involving a plurality of type-forms different from the slugs herein shown. It will also be seen that the plurality of typeforms could be simultaneously finished in ways other than the cutting of the feet herein shown in accordance with the invention here in set forth.
